1353 for being rotatablely connected fixed plate 11, and there are two the usually tools of gap-regulating portion 1, is separately positioned on the two sides in sieve plate portion 3, and
It is two sides of the mirror settings in sieve plate portion 3, each gap adjustment bar 135 can be connected with two sliding axles, that is to say, that first
The first sliding eye 1351 and second that sliding axle 133 and second sliding axle 134 can be inserted into first gap adjustment bar 135 respectively is sliding
Hole 1352 is moved, also, second sliding axle 134 can also be inserted into first sliding eye 1351 of second gap adjustment bar 135, successively class
It pushes away, the quantity of track 12 and the quantity of sliding sleeve are identical, that is to say, that the corresponding sliding sleeve of a track 12, and gap tune
The quantity of pole 135 one fewer than the quantity of track 12, the first connecting hole 1353 of gap adjustment bar 135 is connected with fixed plate 11
It connects, since gap adjustment bar 135 can rotate, gap adjustment bar 135 can be turned around the axis of the first connecting hole 1353
It is dynamic, it can be attached by way of pin shaft or others between gap adjustment bar 135 and fixed plate 11, as long as between capable of making
Gap adjusting rod 135 is rotated around the axis of the first connecting hole 1353；The effect of angle adjustment 2 is to adjust multiple sieves 32
Angle, angle adjustment 2 include adjustable plate 21 and multiple regulating members 22, and adjustable plate 21 is fixedly connected on fixed plate 11, are adjusted

The axis of two connecting holes 1354 overlaps, and the other end has angular adjustment bar 222, for connecting one of hole slot 211, adjusts
Section plate 21 is fixedly connected on fixed plate 11, so that gap-regulating portion 1 and angle adjustment 2 be made to form an entirety, each adjusting
One end of component 22 has third connecting hole 221, and sieve plate connecting rod 31 passes through and be fixedly connected on the second connecting hole 1354 and the
Three connecting holes 221, while gap-regulating portion 1 is mobile, the angular adjustment bar 222 of the other end of regulating member 22 is arranged in hole
In slot 211, angular adjustment bar 222 is enable to be moved in hole slot 211, drives regulating member 22 around third connecting hole 221
Axis rotated, make the angular deflection in sieve plate portion 3, adjusted in real time to reach and be able to carry out the angle in sieve plate portion 3
Technical effect；The effect in sieve plate portion 3 is that crops are carried out with threshing processing, and sieve plate portion 3 includes sieve plate connecting rod 31 and multiple sieves
Piece 32, each sieve plate connecting rod 31 are fixedly connected on multiple sieves 32, and each sieve plate connecting rod 31 passes through the second connecting hole 1354
And it is fixedly connected on third connecting hole 221, sieve plate portion 3 is made of multiple sieve plate connecting rods 31 and multiple sieves 32, a sieve plate
Multiple sieves 32 are set in connecting rod 31, also, each sieve 32 is perpendicular to sieve plate connecting rod 31, two adjacent sieves 32
Between have interval, can be inserted into the sieve 32 in adjacent sieve plate connecting rod 31 in interval；In the embodiment of the present invention, pass through
Gap-regulating portion 1 adjusts the gap between threshing cylinder and sieve plate portion 3 in real time, while right by angle adjustment 2 again
The angle of each sieve 32 in sieve plate portion 3 is adjusted, change original sheller unit there are the drawbacks of, make multiple gap adjustments
Bar 135 forms multi link and imitates circular knitting machine structure, gap size problem when effective solution crops threshing, to reach raising
The threshing performance of crops reduces the percentage of damage of crops and the technical effect of percentage of impurity.
Further, as shown in Fig. 1 to Fig. 3 and Fig. 5, the shape of each track 12 is arc line shaped.In the present embodiment,
The shape of track 12 is further defined, since the first connecting hole 1353 of gap adjustment bar 135 is used to be connected and fixed plate 11, because
This, each gap adjustment bar 135 can be rotated around the axis of the first connecting hole 1353, also, each 135 meeting of gap adjustment bar
It is connected with two sliding axles, that is to say, that first sliding axle 133 and second sliding axle 134 can be inserted into first gap respectively
The first sliding eye 1351 and the second sliding eye 1352 of adjusting rod 135, second sliding axle 134 can also be inserted into second gap adjustment
First sliding eye 1351 of bar 135, and so on, so that multiple gap adjustment bars 135 is joined together to form a regular polygon
Part-structure, multiple gap adjustment bars 135 join end to end, it will form the shape of a regular polygon, and the rail of track 12
Mark determines the position of each gap adjustment bar 135, and track is arc line shaped, and the center of circle of track is the axis of the first connecting hole 1353
The heart, in the present embodiment, by limiting the shape of track 12, to further reach between threshing cylinder and sieve plate portion 3
The technical effect that gap is adjusted in real time.
Further, as shown in Figure 1, Figure 2 and shown in Fig. 5, the shape of hole slot 211 is circular arc waist type.In the present embodiment, further
The shape for defining hole slot 211 is circular arc waist type, since one end that the movement of gap adjustment bar 135 will drive regulating member 22 turns
Dynamic, the other end of regulating member 22 is arranged in hole slot 211, and therefore, the rotational angle of each sieve 32 is controlled by hole slot 211
System, since sieve plate connecting rod 31 passes through the second connecting hole 1354 and is fixedly connected on third connecting hole 221, regulating member 22 can be around
Third connecting hole 221 is rotated, and therefore, the rotation center of circle of hole slot 211 is the shaft core position of third connecting hole 221, and hole slot
211 length can be set according to the angle that regulating member 22 rotates, and the angle that regulating member 22 rotates is bigger, hole slot
211 length is longer, in the present embodiment, by limiting the shape of hole slot 211, adjusts multiple sieves in real time to further reach
The technical effect of 32 rotational angle
Further, as shown in figs. 4 and 7, there are multiple 4th connecting holes 111 and multiple 5th connections in fixed plate 11
Hole 112, also has multiple 6th connecting holes 212 on adjustable plate 21, and each 4th connecting hole 111 is fixedly connected on each track
12, each 5th connecting hole 112 connects one to one with each 6th connecting hole 212, for fixing fixed plate 11 and adjustable plate
21.In the present embodiment, fixed plate 11 and adjustable plate 21 are further defined, the effect of multiple 4th connecting holes 111 is retaining rail
Road 12 needs for each track 12 to be fixed in fixed plate 11, makes each gap adjustment bar 135 after the track of track 12 determines
It can be rotated according to the camber line that track 12 is set, each 5th connecting hole 112 is corresponded with each 6th connecting hole 212
Connection, that is to say, that the axis of the 5th connecting hole 112 and the 6th connecting hole 212 overlaps, and makes fixed plate 11 and adjustable plate 21
Relative position be fixed, also, the first connecting hole 1353 of gap adjustment bar 135 also axis with the 5th connecting hole 112
It overlaps, therefore, the axis of the first connecting hole 1353, the 5th connecting hole 112 and the 6th connecting hole 212 overlaps,
It can be attached by straight pin between first connecting hole 1353, the 5th connecting hole 112 and the 6th connecting hole 212, it can also be with
It is attached by other pin shafts, as long as fixed plate 11 and the relative position of adjustable plate 21 can be made to be fixed, and is made
Gap adjustment bar 135 can be rotated around the axis of the first connecting hole 1353, optional multiple 4th connecting holes 111 and multiple
